The Echo Dot is meant to be a low-cost way to get Amazon’s Alexa assistant into your home. While it’s not quite as powerful a speaker as the standard Echo (it does have a speaker), it offers all of the same features as its taller brethren. That includes support for services like Uber, Spotify, and connected devices from the likes of WeMo and Philips Hue, as well as support for Alexa phone calls and messages.
